compare mcumgr image hash with compiled/signed .bin/.hex hash

florian.gaertner@...
 

Hi there,

Is there an easy way to compare the mcumgr image hash response to the hash of the hex or binary file (signed or unsigned)?

# mcumgr --conntype ble --connstring ctlr_name=hci0,peer_name='Zephyr' image list

e.g. with
# sha256sum signed-image.hex

Best regards

How to integrated BLE central code with RPL Node example? #nrf52832 #zephyrbluetoothmesh

Akash Naidu <akashnaiduece@...>
 

Hi All,
I have been working on RPL node example(which is in zephyr/samples/net/rpl_node), to work it as both central and peripheral concurrently.
I have successfully integrated peripheral code with RPL node example, and device has been able to Advertise and able to establish the connection also.
To act as peripheral, i have edited "prj.conf" file and has been working as peripheral.
If i do same thing for central, device was not getting enter into scan mode.
my aim is, each device should act as peripheral and central and on top of BLE links will send IPV6 packets by using RPL protocol.

could you please help me to integrate Central(nrf52832 DK) with RPL_node?

Thanks in Adavnce.

Disabling Multithreading

Raj Gundi
 

Hi Carles,

 

I am trying to build Zephyr to fit in a memory constrained device of 64kB. My device doesn’t require multithreading and hence I disabled multithreading to save on the memory. However, this is throwing me exceptions since I have UART and SPI Flash drivers enabled. It appears the semaphore accesses in those drivers are not “single-thread” aware. Is there anything that can be done to work-around this? Does just “nop”ing it out suffice? Please let me know.

 

Regards,

Raj
problems linking custom board (terasic sockit) and soc for altera nios2

mazaun@...
 

Hi,
I'm working on creating a custom out-of-tree board with soc for the Terasic SocKit board. Though there are certainly many things not done correct yet, I'm currently stuck at linking the simple hello_world sample. I uploaded the code to https://github.com/mzau/altera-sockit-zephyr. Please see https://github.com/mzau/altera-sockit-zephyr/tree/master/hello_world/README.md  for details.

Any help or hints are very appreciated :)

Re: To current Zephyr HTTP API users

Hello,

currently Zephyr has HTTP server & client APIs that are built on top

Would there be anyone interested in writing such HTTP server / client
APIs?
Well, I kinda was interested in this, given all my criticism of the
older API and implementation. But I'm in reservations after the TLS
zstream case, where a bunch of effort was spent to do it right, and all
that went to /dev/null.

If there are no users for existing HTTP APIs, we could also
optionally start to deprecate them.
IMHO before we provide a replacement, we should not deprecate
anything.

The new HTTP APIs could also be
based to some existing open source library if you know any.
I think that given that we have "in house" implementation of COAP,
LWM2M, MQTT, that it would be indeed a refreshing change to not try to
invent our own API, but try to port an existing. Well, at least to
survey the landscape trying to find one which would be suitable for our
code/RAM size requirements.

So please
raise your hand if you could help here.
So, I think we should decide if it would be OK to bet on 3rd-party
lib at all, then focus a call exactly like that: Are there suggestions
of existing lib to port, satisfying our requirements (which is, again,
being small)?

Myself, I think my plate is more than full for 1.14, and I already
subscribed to port another lib to Zephyr (OPC-UA). However, if we agree
on 3rd-party solution to be OK in principle, I start surveying too in
the background in the meantime.



Cheers,
Jukka

Re: Mesh: Limit of PDUs sent within a moving 10-second window

We’re not trying to enforce anything like that as receivers. As senders it’s also not really possible to exceed it currently. Even with the minimum advertising interval (20ms) and default Network Transmit State (with 2 retransmissions) the stack takes 120ms to send out any given PDU, so even if you had a continuous flow of outgoing packets you’ll still be below the recommended maximum (note that it’s a recommended, not required one since the spec uses “should” for this.

In the future, once we have Mesh vendor HCI extensions in place we might be able to do send out packets more efficiently, and then we can revisit this issue to see if some enforcement needs to be done in the stack or whether to leave this up to the application.

Subject: [Zephyr-devel] USB controller driver usb_dc_ep_write

 

Hi all,

I see many USB controller drivers implement usb_dc_ep_write function with one copy, copy the data (passed to usb_dc_ep_write) to one self’s buffer then do the transfer.

Do I need do this when implementing one new USB controller driver?


There is no requirement to copy the data, but usually, usb device drivers copy the data to the controller FIFO.

Does the Zephyr USB stack limit the data (pass to usb_dc_ep_write) is in RAM?

 
There is no defined data size limit when calling the function, but at then end, driver decides how much data is written (e.g. size of the FIFO).

The function prototype is as follow:

int usb_dc_ep_write(const u8_t ep, const u8_t *const data,

                  const u32_t data_len, u32_t *const ret_bytes)


For USB users (e.g. class/gadget drivers, app) the high level usb_transfer() function can be used to execute USB data transfer.

Regards,
Loic

When could we expect that blemesh code will be usable in c++.
Most header files in zephyr are compatible with c++ but not ble mesh headers.
No #ifdef __cplusplus in headers.

Hi


There is a platform_whitelist in the sample.yaml file. In your case:

"platform_whitelist: frdm_k64f "


So you need this nxp board or have to port the sample to another board.

Re: CONFIG_BT_PRIVACY cannot be enabled with Hci_uart sample #nrf52832 #hci

Carles Cufi
 

Hi there,

 

If you are building the hci_uart then CONFIG_BT_PRIVACY is irrelevant because it’s only tied to the Host. What you need is CONFIG_BT_CTLR_PRIVACY, which enables privacy in the controller.

Subject: [Zephyr-devel] CONFIG_BT_PRIVACY cannot be enabled with Hci_uart sample #nrf52832 #hci

 

Hi guys, I met a problem here and hop anybody can help.

I want to enable the config CONFIG_BT_PRIVACY, and according to the official document, the config depends on BT_SMP BT_CONN BT_HCI_HOST BT_HCI and BT。 So I have to set all these configs above to  "y"  first, but BT_HCI_HOST conflicts with config BT_HCI_RAW and I have to disable BT_HCI_RAW config if I want to enable BT_HCI_HOST.  But the hci_uart sample will compiled with errors if BT_HCI_RAW is disabled.

So I wonder how to enable CONFIG_BT_PRIVACY in hci_uart sample ?

thanks

config BT_HCI_HOST

 

 

 

 

# Virtual/hidden option to make the conditions more intuitive

 

 

 

bool

 

 

 

default y

 

 

 

depends on !BT_HCI_RAW

 

 

 

select POLL

 

 

 

 
config BT_PRIVACY
    bool
    prompt "Privacy Feature" if BT_SMP && BT_CONN && BT_HCI_HOST && BT_HCI && BT depends on BT_SMP && BT_CONN && BT_HCI_HOST && BT_HCI && BT help Enable local Privacy Feature support. This makes it possible to use Resolvable Private Addresses (RPAs).
